The card LEDs are okay, but you

If the card LEDs appear to be okay:

 

can’t communicate with other

1) Verify that the cable being used

 

systems.

 

complies with the IEEE 802.3u-1995

 

 

 

 

standard.

 

 

2) Ping the broadcast address for the

 

 

card, and check to see if the activity

 

 

light on the hub blinks. Other active

 

 

hosts must be connected to the hub or

 

 

else the activity light will not blink.

 

 

3) If the activity light on the hub does

 

 

not blink, and there are other active

 

 

hosts connected to the hub, open

 

 

another window and enter: netstat

 

 

-i 1

 

 

Try the broadcast ping again. The

 

 

transmitted packets counter should start

 

 

to increment. If the counter does not

 

 

increment, then there is an IP

 

 

configuration problem.

 

 

4) If the counter does increment, but the

 

 

activity light on the hub does not blink,

 

 

check the card’s activity light. If it is

 

 

blinking, the problem is likely with the

 

 

hub or connection to the hub. If the

 

 

activity light on the adapter is not

 

 

blinking, then there may be a problem

 

 

with the driver or the card. Contact HP.

 

 

 

 

Link LED off.

Check RJ-45 connector, switch, hub,

 

 

and cable.
